  Square roots of non-perfect square , Mathematics  Tricks and Fun 23 Hello friends,today we are going to study how to derive  the square roots of nonperfect squares. This is the 23rd class of Mathematics Tricks and Fun. I am Dr Prema B Sejekan.  In this example we have to derive the square of 52443907.This is an eight digit number. So in the answer we will have 4 digits and rest will be in decimals.Since even number take first two digits ie 52.Find a digit the square of which is near to 52 ie 7.Now put seven on quotient side and 49 placed below 52 balance 3 in front  of 4. Double of 7 ie 14 is taken as the divisor place it on the outer side and diary dividing 34 with 14 we will put 2 on quotient side and 28placed below 34 balance 6 we  will put in front of 4 to form 64.Now square of 2 is 4 ,  deduct 4 from 64 ,we will get 60 which when divided by  14 gives 4 as quotient.4×14=56.balance of 56 from 60  is 4 placed beside 3 to g...
